Comparative Study of the Influence of PPS, PAEK, and PEEK Thermoplastic Matrices on the Fatigue Mechanical Behavior of Carbon Fiber Reinforced Composites

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Structural thermoplastic composites have attracted increasing interest in engineering applications due to their excellent mechanical properties and recyclability. This work aims to contribute to this field by investigating the influence of poly(ether ether ketone) (PEEK), poly(aryl ether ketone) (PAEK), and poly(phenylene sulfide) (PPS ...

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI

Groundwater, EarlyView.
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

Hydraulic Strategies of Cool‐Temperate Trees and Lianas Against Freeze–Thaw Embolism: Is Cold Winter More Severe on Lianas?

Plant, Cell &Environment, EarlyView.
ABSTRACT Lianas are abundant and influential in tropical forests but decline sharply in cooler regions. This pattern has been attributed to their reliance on a small number of large vessels, which are vulnerable to freeze–thaw embolism. However, the hydraulic functioning of lianas in cooler regions remains poorly understood.

Hydraulic flushing technology and its practice in outburst coal seam with high gas and low permeability

, 2015
Hydraulic flushing technology can rapidly and effectively eliminate coal and gas outbursts and improve the permeability of a coal seam. Its effect mainly depends on the technical parameters of hydraulic flushing.

Long‐term stability of transcrestal sinus augmentation

Periodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...
